Which foliar fertilizer is best for high-yield peanuts? The latest recommendations are here
Foliar fertilizer is a type of fertilizer in which nutrient elements are applied to the surface of crop leaves and perform their function through leaf absorption. As a supplement to the plant's absorption of nutrients, it makes up for the deficiency of nutrient uptake by the root system. It is worth noting that foliar fertilization cannot replace soil fertilization. Now let us take a look at which foliar fertilizer is best for high-yield peanuts!
Which foliar fertilizer is best for high-yield peanuts?
Peanut foliar fertilizer has the effects of high fertilizer absorption and utilization rate, saving fertilizer, and significantly increasing yield. Major elements such as nitrogen, phosphorus, and potassium, as well as trace elements such as calcium, molybdenum, boron, manganese, and iron, can all be applied to the foliage. Foliar application of nitrogen fertilizer significantly increases the number of full pods per plant. Foliar application of phosphorus fertilizer generally can increase yield by 7 to 10%, and foliar application of micro-fertilizers such as aluminum, boron, manganese, and iron generally can increase yield by 8 to 10%. When selecting foliar fertilizer for peanuts, it is best to choose a brand registered with the Ministry of Agriculture, and it is better to choose a dedicated foliar fertilizer.
Principles of peanut fertilizer demand
1. Major elements: The proportion of the three major elements nitrogen, phosphorus, and potassium required by peanuts is 3:0.4:1. Nitrogen is needed the most, potassium second, and phosphorus the least. Therefore, when applying major element fertilizers, nitrogen should be the main focus, with an appropriate amount of potassium.
2. Trace elements: Peanuts have the greatest demand for several elements such as calcium, sulfur, and magnesium. Calcium can promote faster growth of peanut plants, sulfur can increase the protein content of kernels, and magnesium can promote the normal formation of chlorophyll in peanuts.
How to use peanut foliar fertilizer
1. Fertilizer dilution: Take 35 grams of concentrated liquid fertilizer and add 20 kg of clean water, dissolve and stir evenly. It is best to use tap water; pond water and rainwater contain more impurities.
2. Foliar spraying: When spraying peanut foliar fertilizer, focus on the underside of peanut leaves and spray evenly. Choose a sprayer with a good atomization effect to facilitate leaf absorption.
3. Spraying time: The best time to spray peanut foliar fertilizer is from after flowering to the beginning of pod formation, spraying once about every 10 days, which can achieve the effect of enlarging the pods and increasing yield.
Precautions for peanut foliar fertilizer
1. The fertilization time should be determined according to the growth condition and growth stage of peanuts, and generally should be applied in the late growth stage.
2. Choose a windless cloudy day or a sunny day before 9 a.m. and after 4 p.m. for spraying to increase leaf absorption and prevent damage to the leaves.
3. Strictly control the spraying concentration; a high concentration can easily damage the leaves and cause fertilizer damage.
4. When spraying peanut foliar fertilizer, spray evenly and finely, and spray both the front and back sides of the leaves.
